The circuit shown in the given figure is a model of a solenoid, such as that used to engage the gear of a car’s starter motor to the engine’s flywheel. The solenoid is constructed by winding a wire around an iron core to make an electromagnet. The resistance R is that of the wire, and the inductance L is due to the electromagnetic effect. When the supply voltage vs is turned on, the resulting current activates the magnet, which moves the starter gear.
Obtain the model of the current i given the supply voltage vs.
A coil of resistance 100W is placed in a magnetic field of 1mW. The coil has 100 turns and a galvanometer of 400W resistance is connected in series with it. Find the average emf and the current if the coil is move in 1/10th second from the given field to a field of 0.2mWb.
